  • Task 7 : Method Of An Copper Sulphate Solution Into A 100cm3 Beaker

    1525 Words  | 7 Pages

    Method: 1. Firstly you need to need to measure accurately 0.50g of your copper sulphate solution into a 100cm³ beaker 2. Then add about 50cm³ of distilled water ensuring you continue to stir until crystals have dissolved. Then transfer the solution into a 100cm³ volumetric flask 3. Next rinse out the beaker with small amounts of distilled water and transfer the washings to the volumetric flask to ensure none of the solution is wasted affecting the end result. 4. Once the beaker is sufficiently washed

  • The Chemistry Of A Heating Bath

    1054 Words  | 5 Pages

    A heating bath is used in the laboratory to allow the chemical reaction to occur at an elevated temperature around 1000C. The beaker is a glass vessel which contains the chemical solutions for the purpose of coating. It is placed in the electroless bath where the chemicals are being heated up. The glass rod is used to stir the chemical where the magnetic stirrer is not necessary. The tongs are used to lift the bath after the coating is completed. Tri-sodium citrate and thallium acetate are the chemicals

  • Mixtures, Explain Whether It Is A Solution Or A Heterogeneous Mixture

    1510 Words  | 7 Pages

    42. For each of the following mixtures, explain whether it is a solution or a heterogeneous mixture. For the solutions, identify the solute and the solvent. a) Cloudy pond water – heterogeneous mixture, this is because it is cloudy, solute is dirt particles - in the water there is clay and humus. b) Apple juice - is a homogeneous solution, water is the solvent there are organic acids, sugars and gums c) Rain water – is a homogeneous mixture, rainwater is nearly a distilled water. The mixture is

  • Solubility Enhancement Of Fenofibrate By Solid Dispersion Technique

    1872 Words  | 8 Pages

    Solubility Enhancement of Fenofibrate by Solid Dispersion Technique 1. Introduction: Oral route of drug administration is one of the preferable methods of drug delivery due to its convenience, ease of administration and a more effective medication system than other drug delivery systems in terms of patient’s compliance. However, not all drugs are of same solubility; some poorly soluble hydrophobic drug often generates certain complexities in formulation development as well as other clinical research

  • Osmosis lab/ concentrations of solutions effect on potatoes mass.

    1406 Words  | 6 Pages

    "Do different concentrations of solutions determine the mass of a potato?" Introduction: The way to get the full results of this lab was through the process of osmosis. Osmosis is the movement of water across a membrane into a more concentrated solution to reach an equilibrium. When regarding cells osmosis has three different terms that are used to describe their concentration. The first of these words is isotonic. Cells in an isotonic solution show that the water has no net movement and the amount

  • The Viscosity of Liquids

    lecture, you will be able to Define viscosity and viscosity coefficient Outline the method to measure viscosity using Ostwald viscometer Determine the average molecular weight of a polymer Determine the surface concentration of 1-butanol in aqueous solution Measure the distribution coefficient of a solute betweenn two solvents 39.1 Introduction Viscosity, one of the transport properties, arises because of intermolecular attractive and relatively long-range forces. Viscosity coefficient ([pic])

    Materials & Methods In the osmotic lab seven cups , a marker, metric ruler, digital balance, paper towels, a knife and seven cups containing solutions 0.0, 0.1, 0.2, 0.3, 0.4, 0.5, 0.6m of sucrose were used in the experiment. The marker was used to label the seven cups with the seven different concentrations of sucrose . A cork borer was used to cork the potato and then the metric ruler was used

  • Betacyanin Essay

    1324 Words  | 6 Pages

    Effects of temperature manipulation and solution treatment on the Beta vulgaris craca plant cell membrane and the change of the concentration of betacyanin when placed under these various stresses Introduction: The Beta vulgaris craca plant, commonly referred to as the beet root contains a pigment, red in colour, called betacyanin. The betacyanin’s containment within the cells of the beet root cell relies on the stability of the plant’s membrane structure. The manipulation of the cell’s membranes

  • Investigate the Osmosis in Potato Rods in Various Concentrations of Salt Solutions

    2300 Words  | 10 Pages

    Concentrations of Salt Solutions Introduction: Osmosis is the movement of water molecules across a partially permeable membrane from a region of high water potential to a region of low water potential. It can be affected by several different variables including concentration of salt solutions. When a plant cell is put in pure water it will become turgid and it will not burst due to the presence of a cell wall and a large permanent vacuole and when it is put in a concentrated solution it will be plasmolysed
